The COVID-19 outbreak caused short-term disruptions in the supply chain of fresh agricultural products (FAPs), which exposed the vulnerability of the existing FAP supply chain. With pandemic control being widely coordinated, the supply chain of FAPs was gradually optimized and improved. However, after the outbreak of COVID-19, achieving an effective supply of FAPs in future pandemics has become a key issue. The present work therefore aimed to construct a three-level supply chain based on the Stackelberg game model, consisting of suppliers, third-party logistics (TPL), and retailers, to guarantee the supply of FAPs. COVID-19 pandemic factors such as virus infection coefficients and pandemic prevention efforts were fully integrated into the model.
Compared with the wholesale prices of FAPs, preservation efforts and pandemic prevention efforts have huge impacts on the retail prices of FAPs. When suppliers are in the leading position, the quality assurance effort level is positively correlated with the optimal profit. Compared with this situation, when FAP retailers are in the leading position, TPL providers show higher levels of pandemic prevention effort and FAP preservation effort. With an increase in consumer preference for pandemic prevention, the profits of supply-chain members when FAP retailers are in the leading position will gradually increase.

This study aimed to explore the experiences of Iranian nurses who were caring for patients with HIV.
A focused ethnography approach was used. Participants consisted of 12 nurses working in teaching hospitals affiliated to Urmia University of Medical Sciences and recruited by purposeful sampling. Semi-structured interviews, field observations and field notes were used for data collection. Data were analysed employing content analysis.
Three main themes emerged from the analysis of the participants' experiences of providing care to patients with HIV 'excessive fear of being infected', 'concerns about the possible consequences' and 'lack of self-confidence in care provision'.
Nurses have experienced a great deal of fear of self and cross-contamination when providing care to people living with HIV. Social stigma and discrimination against people living with HIV amplified the nurses' experience of fear. Providing appropriate education and training for nurses can improve their attitudes, emotions and self-confidence while providing care to such people and increasing the quality of care provided.
Planning more educational programmes focusing on improving their misunderstandings about HIV could result in positive outcomes for nurses to provide high-quality care and for people living with HIV who receive this care. The healthcare system should consider the culture of care provided by nurses to these people.

While the economic transformation was extensively studied, social transformation was not. In this paper, we use for the first time harmonized household surveys covering the period 1988-2013 to study the changes in the characteristics of the richest 5 percent of China's urban population. We find that it changed from being composed of high government officials, clerical staff, and workers in 1988 to professionals and small and large business owners in 2013. The educational level of the top group increased substantially. Membership in CCP has a positive (albeit small) effect on one's income but is particularly valuable to large business owners.Crop phenology change is co-determined by climate change and adaptation strategies, such as crop management, but their combined and isolated impacts on rice phenology are still unclear. Quantifying the impacts and identifying the main contributors are critical to food security under climate change. Thus we distinguished and quantified the relative contribution of climate change and crop management to rice (Oryza sativa L.) phenological changes in China from 1981 to 2010, using a first-difference multivariate regression method.
Rice phenology has changed over the past 30?years in China. The mean length of the phenological stage from emergence to transplanting was shortened, whereas the mean length of the stage from transplanting to heading, from heading to maturity, was prolonged. The relative contribution of crop management was greater than that of climate change for single and late rice, which took up over 90% of the total change in certain phenology stages. Among the climatic factors, temperature was the dominant contributor, which accounted for more than 50% of the change in rice phenology. The stage from transplanting to heading of early rice and late rice had strongly negative sensitivities to increasing temperature.
Crop management has offset the adverse effects of climate change on single and early rice phenology in China over the past 30?years to some extent, while further adaptation measures such as adjusting sowing date, shifting rice varieties, applying nitrogen fertilizer and irrigation should be applied to late rice in southern China, especially in a warmer future. © 2021 Society of Chemical Industry.
